Description An experiment was conducted to study the effect of sex on growth pattern and carcass characters of commercial broilers. One hundred and twenty numbers of day-old chicks were wing banded, weighed and reared up to 40 days of age. The body weight was individually recorded from all the birds on 7, 14, 21, 28, 35 and 40 days of age to assess the influence of gender on body weight. At the end of the experiment 12 males and 12 females were subjected to slaughter studies to assess the carcass characters. The body weight between males and females were similar up to 14 days of age and thereafter, males recorded significantly (p<0.01) higher body weights on 21, 28, 35, 40 days of age, weighing 35.79, 107.69, 179.73, 211.88 g respectively higher than females. The ready-to-cook weight (%) and dressed carcass (%) were significantly (p<0.05) higher in males; whereas, New York carcass (%) was significantly (p<0.05) higher in females. Among the cut of parts, the drumstick percentage was significantly (p<0.05) higher in males, whereas, the wings percentage was significantly (p<0.05) higher in females. Among processing yields and losses, only shank & feet and abdominal fat (%) showed significant (p<0.05) difference between sexes; while, feather, blood, head, viscera, kidney and total offal yields had non-significant difference between sexes. Among giblets, only the heart yield was significantly (p<0.05) different between sexes with higher value in females. The results showed that the males attain marketable weight early, therefore can be marketed early. The males can be slaughtered earlier than females for producing specialized products from drumstick; whereas, females can be slaughtered early to harvest drumette.
